If you actually have one of these - http://arduino.cc/en/Main/ArduinoBoardNano - please explain where the RX0/TX1 pins are. The Nano, being 168/328 based, only has a single hardware serial port, connected to the pins marked D0RX and D1TX. You could use SoftwareSerial if you wanted additional serial IO.

I thought that RX0 is D0RX and TX1 is D1TX...

So... Serial.print() is using this pins by default?The Tx LED shouldn't blink?
